Patent CA-2197574-A1 (CA)
Title: Process of producing methanol
Inventor: KOENIG PETER
IPC: C07C31/04
Filed: 1997-02-13
Abstract: Methanol is catalytically produced from a synthesis gas containing hydrogen and carbon oxides on copper-containing catalysts at pressures in the range from 20 to 120 bar and temperatures in the range from 130 to 350°C. The synthesis gas is first of all passed through a first synthesis reactor, in which the catalyst is provided in tubes surrounded by water as a coolant which is boiling at an elevated pressure. From the first reactor a first mixture containing gases and methanol vapor is withdrawn and passed through a second synthesis reactor. In the second reactor the catalyst is cooled with synthesis gas.

Title: System for harvesting crops by combing
Inventor: CHUKSIN PETR IVANOVICH
IPC: A01D41/06
Filed: 1995-10-23
Abstract: The object of the invention is to reduce wastage from the crop and simplify the design of the combing unit. The essence of the invention lies in the fact that in the combing unit, the teeth of the working combing element are arranged in rows along the direction of travel and the upper rim of the front wall of the receiving chamber takes the form of resilient teeth whose ends are configured between lateral edges of the teeth of the working combing element; the angle of inclination of the front wall of the receiving chamber to the horizontal plane is greater than the natural slope angle of a heap of cereal, leguminous crop or grass seed.

Title: Compact spill containment pan
Inventor: BISHOP MERRILL E
IPC: F16N31/00
Filed: 1997-10-02
Abstract: Spill containment apparatus especially adapted for use at a railroad siding to catch inadvertent chemical spills includes a shallow, rectangular pan having upstanding, opposed sidewalls and upstanding, opposed endwalls.  Flaps are pivotally connected to the sidewalls near the upper edges thereof.  The flaps can be moved from a first position where they are stored inside the pan to a second position where they extend laterally outside the pan and over the railroad tracks.   A longitudinally movable cover is provided for the pan, the cover being mounted on tracks for back and forth movement between a first position where the pan is covered to a second position where the pan is exposed.   In the second position of the cover, the flaps are permitted to move between their first and second positions.  Because the flaps can be stored inside the pan, the size of the pan when not in service is relatively small.  Because the flaps can be extended in use, the effective surface area protected by the pan is quite large.

IPC: A61B17/16
Filed: 1997-10-24
Abstract: A machining assembly, including a novel broach design, are disclosed for preparing a femoral medullary cavity (C) for receipt of a femoral prosthetic stem (S), wherein the configuration of the implantation site allows for the neutral alignment of the prosthesis (S) within the medullary cavity (C) for improved rigid fixation of the stem (S) therein. Aspects of the inventive machining assembly include a novel broach (10) comprising a proximal lateral recess (13) that allows for initial avoidance of the greater trochanter during implantation, thereby resulting in the preparation of a neutrally aligned cavity with respect to the broach. The machining assembly also includes a guide (200) and second cutting instrument (208) for removing the bone of the greater trochanter (1 ) once neutral alignment between the medullary cavity (C) and broach (10) are achieved for the subsequent implantation of a neutrally aligned femoral prosthesis (S).

Abstract: An O/W emulsion composition for eye drops comprising a medicine selected from among fluorometholone, clobetasone butyrate and clobetasol propionate, a phospholipid, liquid paraffin, and water. The composition is excellent in the solubility of fluorometholone, clobetasone butyrate and clobetasol propionate in the lacrimal fluid. Accordingly, it is expected to achieve in a small dose an anti-inflammatory activity comparable or superior to those of the conventional preparations, thus being excellent economically. It is also expected that fears of systemic side effects accompanying the intraocular administration of these medicines are relieved thereby.

Patent CA-2233996-A1 (CA)
Title: An energy storage and conversion apparatus
Inventor: FULLWOOD DAVID TOD
IPC: F16C35/06
Filed: 1996-10-01
Abstract: An energy storage and conversion apparatus (1) comprising a containment (5) defining a vacuum chamber (7), a support shaft (9) within the vacuum chamber (7), a stator (11) on the shaft (9) and a cylindrical rotor (13) which, in use, is driven by the stator (11) to store energy as kinetic energy of the rotor (13) and acts with the stator (11) as a generator to release energy, wherein the rotor (13) is supported by the shaft (9) via an end cap (29) which, as the rotor (13) speed increases, deflects from a conical shape towards a planar shape. As a result, failure of the apparatus (1) does not occur when the rotor (13) expands due to centrifugal forces. Further, the position of the rotor (13) relative to the stator (11) and magnetic bearing on the shaft (9) is kept essentially constant, even if the length of the rotor (13) decreases due to Poisson effects.

Patent CA-2246698-A1 (CA)
Inventor: JUSKAITIS RIMVYDAS
IPC: G02B21/00
Filed: 1997-02-21
Abstract: A confocal microscope comprises a light source, focusing means, a detector and an encoded mask (17). The light source illuminates the mask (17) and the encoded light is then focused on a specimen. Light the from the specimen is then decoded, by either the same or a separate complementary mask, before being detected, for example by a camera. The mask (17) is encoded with a pattern which generates a combined confocal and non-confocal image and the confocal image is subsequently extracted from the combined image. This means that confocal images of different regions of the specimen can be produced simultaneously which in turn enables real-time confocal imaging of the specimen. In addition, as the microscope is no longer restricted to delta correlated images, an improvement in the light budget can also be achieved.

Filed: 1998-09-16
Abstract: A conveyor system comprises a pair of side-by-side conveyors adapted to move articles such as baggage or cargo in opposite directions simultaneously,  preferably at the same elevation,  and linked together by an endless belt.         The endless belt is directed from the exit of one conveyor to the entrance of the other conveyor and from the exit of the other conveyor to the entrance of the one conveyor via a pair of conveyor twist assemblies which maintain the baggage carrying surface in an upward orientation on both conveyors.   The twist assemblies can employ vertical or horizontal  rolls  to attain the direction change of the endless  belt.    Staggered  idler  rolls  can  be  arranged beneath the two conveyors for belt support and reduction of vibration caused by belt travel.  The side-by-side conveyor system  is  particularly  useful   in  multiple   stacked arrangements in tunnels for airports.

Inventor: SWEET PAUL W
IPC: F04D29/04
Filed: 1998-09-29
Abstract: In order to accommodate a labyrinth seal whose diameter is too large to form a gas passage using conventional techniques, the labyrinth seal is made in two parts. A first part is an inner ring whose outer diameter is sufficiently small so as to permit the forming of a passage therein with conventional techniques. The second part is anouter ring which can then be fastened to the inner ring so as to then extend, incombination, to the radial extent necessary to complete the sealing engagement with an adjacent element. The outer and inner rings are preferably interconnected by way of an interference fit.
